What is the 9 dot challenge?
The nine-dot problem (Maier, 1930) requires that nine dots arranged in a square be connected by four straight lines drawn without lifting the pen from the paper and without retracing any lines (Figure 1).
Can you solve the 9 dot problem connect all nine dots with four straight lines and without lifting pen or pencil?
Get a pen and some paper and copy the nine dots arranged in a square below. To solve the problem, you need to join all nine dots by drawing no more than four straight lines. The straight lines must be continuous – i.e. you must not lift your pen from the paper once you start drawing.
Can you go through all 9 dots with four straight lines?
One classical example is where nine dots are arranged on the sides and the center of a square as in the picture below. The problem is to connect the dots with no more than 4 straight lines without lifting your hand from the paper. The solution lies in the observation that it’s permissible to cross square boundaries.
How do you do the 9 dots?
The rules are simple; connect all 9 dots using a maximum of 4 straight lines without lifting your pen off the paper or retracing back over an existing line. Most people will see a square and mentally add lines around it creating the context with which to solve the puzzle.

What is the solution to the nine dot problem?
The solution involves looking outside the two-dimensional sheet of paper on which the nine dots are drawn and coning the paper three-dimensionally aligning the dots along a spiral, thus a single line can be drawn connecting all nine dots – which would appear as three lines in parallel on the paper, when flattened out.
Can you draw 4 straight lines with 9 dots?
Draw 4 straight continuous lines without lifting the pen from the paper and make sure that the lines pass through each of the nine dots. This is just one of the possible answers.
How are the dots arranged in the Nine Dot Problem?
